If you’ve been hitting the gym for a while but your chest growth has plateaued, the problem likely isn’t your effort—it’s your technique. Most lifters treat the dumbbell press as a second-tier movement to the barbell bench press, but when done correctly, it can be a superior tool for hypertrophy.

In a recent breakdown, Dr. Milo Wolf shared the exact technical keys needed to stop leaving gains on the table. Whether you’re a beginner or a seasoned lifter, these tweaks will help you maximize the “stretch-mediated hypertrophy” that drives real muscle thickness.

1. The Foundation: Leg Drive and Stability

Gains start from the floor up. Many beginners let their feet move around, which creates an unstable platform for heavy pressing.

• The Glute Hack: Place your feet out as far as is comfortable. This naturally activates your glutes and creates a rock-solid base.
• The Knee Rule: Aim to have your feet directly underneath your knees. This allows you to use your quads to stabilize the movement without the discomfort of having your feet too far back.
• Drive Through the Heels: To keep your lower body locked in, focus on pushing through your heels throughout the entire set.

2. The “Innermost Grip” for Maximum Stretch

The biggest advantage of dumbbells over a barbell is the increased range of motion. To exploit this:

• Grip Positioning: Instead of grabbing the center of the handle, try grabbing the innermost part of the knurling (closest to the weight plate).
• The “Thumbs Up” Cue: By holding the inner part and angling the dumbbells slightly so your thumbs point up, you can get the weights deeper toward your chest before they touch your body. This extra depth translates to a significant increase in pec stretch.

3. Rethinking the “Tuck vs. Flare” Debate

You’ve probably heard that you must tuck your elbows to hit the upper chest. Dr. Wolf is skeptical. While minor angles might change fiber alignment, the most important factor for growth is training the muscle close to failure.

• The Armpit Target: Instead of bringing the dumbbells straight down to your mid-chest, try to bring them outwards and toward your armpits.
• Why it works: Moving the weights outward increases the stretch on the pecs, which research shows is a primary driver for muscle growth.

4. Common Mistakes That Limit Your Progress

If you want to see results, you have to prioritize technique over load.

• Cutting Range of Motion: Lifters often go too heavy and perform half-reps at the top. Muscles grow best when trained in the stretched position. If you aren’t going all the way down, you’re missing the most productive part of the rep.
• Standardize Your Form: Pick a “checkpoint” for every rep—like the dumbbells lightly touching your chest or armpits. This prevents you from slowly shortening your reps as the weeks go by. Tracking your hard sets helps ensure you’re actually progressing, not just going through the motions.
• Don’t Clink the Weights: At the top of the rep, there is no need to touch the dumbbells together. Gravity pulls straight down; moving them inward at the very top provides zero extra resistance for your pecs.

5. Step-by-Step: The Perfect Rep

1. The Setup: Deadlift the dumbbells onto your thighs while sitting.
2. The Kick: Aggressively kick your knees back one at a time to get the weights to your shoulders as you lie down.
3. The Descent: Angle the dumbbells “thumbs up,” bring them toward your armpits, and pause briefly at the bottom to ensure a full stretch.
4. The Press: Drive the weights up explosively. If you’re struggling near failure, think about bringing the dumbbells “in” slightly as you press to get through the sticking point.

Pro Tip: Lengthened Partials

If you want to push your chest development further, try lengthened partials. Once you hit full-range failure, continue doing reps only through the bottom half of the movement (from the stretch to about 90 degrees). This keeps the tension on the muscle where it is most likely to grow.

Putting It Into Practice

Stop worrying about the weight on the bar and start focusing on the stretch in your pecs. Quality reps with proper depth will outperform heavy half-reps every time.

To track whether you’re actually making progress, use SetsApart to log your hard sets close to failure. The app helps you see week-over-week whether you’re adding volume where it counts—not just moving weight.
